Constable used excessive force: CCC

- punches to the man's head and upper body in the sallyport; - the knee drops to the man's head; - gripping onto the man's hair to lift him from the floor; - throwing the man through the charge room door while he was handcuffed behind his back; - dragging the man across the charge room floor by his jaw

The report said the officer's actions constituted misconduct and could constitute a common assault, though the man is yet to be charged.

The officer, whose name is suppressed, resigned in May.

The CCC report also said it recognised that police in Broome face unique challenges, including the highest rate of assaults on police and a significant amount of alcohol-related crime.

The Commission voiced its concern over the adequacy of supervision with nine other officers criticised for failing to intervene and report the two incidents.

Commissioner rejects criticism of supervision

But he has rejected a claim in the report that suggests a systemic failure of adequate supervision within the police force.

"The Corruption and Crime Commission have looked at two incidents," he said.

"There are thousands of lockup admissions in Western Australia every year and I find it difficult how you can draw that kind of conclusion from two incidents alone so we reject that particular suggestion out of hand."
